The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan’s end of life date was August 2018. I know that some users on forums believe that the best OS version for Macs was Snow Leopard. ![]() Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn’t want to switch to new versions, because the old one was rock solid. I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed.
